Description

  The present invention relates to an automatic door activation device, and more particularly, to an automatic door activation device in which a door is opened by a person pressing a activation switch such as a touch switch.

  2. Description of the Related Art Conventionally, in an automatic door activation device, it is well known to open a door via a driving means by turning on an activation switch such as a touch switch attached to or near the door, as disclosed in, for example, Patent Document 1 It is. A specific example of the known starting device is illustrated in the case of the double door A as shown in FIG.

In FIG. 1, reference numeral 1 denotes an invisible building constructed in a full width at the upper part of the entrance of the building. Within the invisible 1, a drive engine (electric motor and speed reducer) M, pulleys 5, 5 and a belt 6 and the like, and a controller 7 is attached. Further, the rails 10 disposed at the lower part of the drive device 3 are supported so that the doors 8, 8 provided at the upper ends of the doors 2, 2 can run, and the doors 2, 2 are interposed via the belt grips 9, 9. By connecting to the belt 6, the doors 2 and 2 are suspended so as to be openable and closable. Furthermore, touch switches 4 and 4 are disposed on the doors 2 and 2.
The automatic door A activates the drive engine M controlled by the controller 7 when the person who is going to pass through the entrance / exit presses the touch switch 2, thereby rotating the belt 6, By pulling the doors 2 and 2 in the relative direction via the belt grips 9 and 9, the doors 2 and 2 are opened while the doors 8 and 8 travel on the rail 11. Then, under the control of the controller 7, the doors 2 and 2 are opened to the fully open position and then perform a predetermined closing operation.

JP-A-5-231065

However, the conventional automatic door activation device is a method in which the drive engine M starts to be activated and opens the doors 2 and 2 by a single ON operation of pressing the touch switch 2. Thereby, in this normal mode, a temporary convenience is ensured for the person who enters / exits the entrance / exit or exits / exits.
However, the normal mode may become defective at the entrance / exit at a specific place. For example, in a nursing home or the like, an inpatient may turn on the touch switch 4 by walking or using a wheelchair and go out without a caregiver without permission. Also, any outsider can easily enter or enter a specific department or room by turning on the touch switch. In order to avoid this, it is sufficient to equip some kind of security device, but this causes a high cost.

  In view of the above-described conventional circumstances, the present invention prohibits the opening of a door by a single ON operation of a start switch such as a touch switch, and then performs a predetermined operation after that, specifically, a re-ON operation after a predetermined time, that is, a start switch It is an object of the present invention to provide an automatic door activation device having a simple security function so that the door is opened only for the first time by two operations or by long-pressing an activation switch.

According to the present invention, in an automatic door starter configured to open a door via a driving means by an ON operation of a start switch provided in or near the door, a predetermined signal is output from an output signal based on the ON operation of the start switch. The door is prevented from being opened by the driving means until time elapses, and the door is opened by the driving means by an output signal based on an ON operation of a start switch within an effective time after the predetermined time has elapsed. (Claim 1).
The output signal based on the ON operation of the start switch may be either an ON signal output when the start switch such as a touch switch is turned ON or an OFF signal output when the start switch is released. A timer for measuring a predetermined time is started by an ON signal or an OFF signal.

The output signal within the effective time has the following two modes.
One of them is an output signal (ON signal or OFF signal) based on the ON operation of the start switch again within the effective time. In this case, the door is opened only when the start switch is operated twice.
The other one is a signal in which the ON signal when the start switch is turned on for the first time is maintained until the valid time (Claim 4). In this case, the door is opened only by a long press operation of the start switch.

  As a specific configuration of the second or third aspect, an ON signal is output to the controller when the start switch is turned on, and the controller controls the output of the start signal to the driving unit. When the start signal is prohibited from being output until the predetermined time set by the timer elapses from the input ON signal, and the ON signal is input within the valid time set by the timer after the predetermined time elapses Further, the prohibition of the output of the start signal is canceled, and the door is opened by the driving means (claim 4).

Therefore, according to the present invention, even if the start switch is turned on, the door does not open for a predetermined time (prohibited time) set by the timer, so that it is recognized as if the door is locked and the door is opened. The specific person who knows the operation can open the door by performing a predetermined operation, for example, the ON operation again within the effective time after the prohibition time has passed. Can be made.
The activation switch is a touch switch, a non-contact proximity switch, or the like, and is attached by being attached to the door itself or a wall surface near the entrance / exit.
This start switch is provided with an inside opening switch attached to the indoor side to open the door from the inside of the room and an outside opening switch attached to the outside of the room to open the door from the outside of the room. It is not necessary to apply to both switches, and it is optional to make one of the normal mode specifications. In this case, the normal mode start switch may be a mat switch or an infrared switch.

The prohibition time and the effective time are set by a timer, and the prohibition time is set to a time sufficient for recognizing that the door is locked (for example, 2 to 7 seconds). The time is set to a sufficiently short time (for example, about 10 seconds) to avoid a human being performing the ON operation, and preferably, the set time can be variably adjusted.
When the start switch is turned on within the prohibited time, the timer is reset (Claim 5). Accordingly, even if the ON operation is performed twice or three times within the prohibition time, the prohibition time is reset each time, and as a result, the prohibition time is extended.

  Further, it is preferable that the start switch is returned to the initial state when the effective time has elapsed. Accordingly, even if the start switch is subsequently turned ON, the prohibition time starts again. Further, the activation switch is preferably a touch switch.

According to the present invention, the door cannot be opened simply by turning ON the start switch attached to the automatic door or the vicinity thereof. Therefore, if applied to the start switch on the inside, the person can go out at a specific place such as a nursing home. It is possible to prevent the inpatients who are worried about going out without permission, and if applied to the outside activation switch, it is possible to restrict unauthorized entry from the outside. In addition, when applied to an outside activation switch in a specific department or room, it is possible to provide an automatic door with a simple and inexpensive security function, such as being able to regulate unauthorized entry of outsiders.
And for a specific person who knows the operation, the door can be opened by operating the start switch twice or by pressing and holding it. Safety can be ensured (claims 1 to 4).

According to claim 5, when the start switch is turned ON within the prohibition time, the timer is reset and the prohibition time is substantially extended. According to claim 6, the start is performed after the valid time has elapsed. Since the prohibition time starts again even when the switch is turned on, it is possible to further ensure the security that prohibits the opening of the door.
Furthermore, according to the seventh aspect, it is possible to use a start switch that is simple and inexpensive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. FIG. 1 shows an outline of an automatic door A for explaining the present invention.
In FIG. 1, the front side of the figure is illustrated as indoor, and the back side of the figure is illustrated as outdoor, and the touch switch illustrated as the activation switch includes the chambers of the doors 2 and 2 in addition to the illustrated inner opening touch switch 4. As shown in FIG. 2, an outward opening touch switch 4a is also provided outside.
Further, although a sliding double door is illustrated in FIG. 1, the present invention can also be applied to a single door or a swing automatic door.

FIG. 2 is a block diagram showing the configuration of the present invention. The inner opening touch switch 4 and the outer opening touch switch 4 a are connected to a controller 7 that controls the operation of the driving device 3. In addition to the illustration, the automatic door A is equipped with an electric lock, a safety auxiliary sensor, and the like, but the portions not directly related to the gist of the present invention are omitted.
The controller 7 includes a control unit 11 that controls the operation of the entire apparatus and includes a motor drive unit 12 that is a motor drive circuit of the drive unit 3, and when an activation signal is output from the control unit 11 to the motor drive unit 12 Then, the drive engine M of the drive device 3 is activated via the motor drive unit 11 to open the doors 2 and 2.
Further, the controller 7 includes a prohibition time timer 13 and an effective time timer 14 for controlling the timing at which the control unit 11 outputs the start signal, specifically, delaying the output timing of the start signal. Further, the controller 7 is provided with a mode selection unit 15.

When the mode selection unit 15 receives an output signal from the touch switches 4 and 4a, the mode selection unit 15 transmits the output signal to the control unit 11 via the prohibition time timer 13 and the valid time timer 14, or the timer 13, 14 is selected to transmit directly to the control unit 11 without going through 14, that is, a door opening / closing start mode is selected, the former being the control mode and the latter being the normal mode.
The mode selection unit 15 is connected to changeover switches 16 and 16a. The changeover switch 16 selects the activation mode of the inner opening touch switch 14, and the changeover switch 16a selects the activation mode of the outer opening touch switch 14a. Like that.
In the present embodiment, the case where the inner opening touch switch 4 is in the control mode and the outer opening touch switch 4a is in the normal mode is illustrated. The normal mode is a method in which the door is opened simultaneously with the ON operation of the touch switch.

Below, the control mode of this invention is explained in full detail.
The prohibition time timer 13 counts when an ON operation such as pressing the inner opening touch switch 4 is performed, and prohibits the output of the start signal from the control unit 11 for a predetermined time, that is, the doors 2 and 2 do not open. It is to make.
The start time of the prohibition time timer 13 is the ON operation of the inner opening touch switch 4, specifically, when the inner opening touch switch 4 is released after the ON signal is output when the inner opening touch switch 4 is pressed. However, in this embodiment, a case of outputting an ON signal is exemplified.
The set time of the prohibition time timer 13 is a time sufficient for recognizing that the doors 2 and 2 are not opened (for example, 2 to 7 seconds). Preferably, the set time can be changed appropriately. In that case, in order to make it possible to change the control mode to the normal mode by changing the set time, it is optional to include the set time of 0 seconds.

The valid time timer 14 and the prohibition time timer 13 are timed after the set time has elapsed, and the output of the start signal from the control unit 11 is allowed for the set time, that is, the opening prohibition of the doors 2 and 2 is canceled. is there.
The set time (effective time) of the effective time timer 14 is fixed to, for example, about 10 seconds, but it is preferable to adopt a variable method that can be changed as appropriate according to the use and conditions of the installation location.
In addition, although the case where two of the prohibition time timer 13 and the valid time timer 14 are used as the timer has been described, a single timer that measures time continuously from the start of the prohibition time until the expiration of the valid time is used, It is also free to detect the prohibition time elapse and effective time start.

Next, the activation operation of the automatic door in the present invention will be described with reference to FIG. The prohibition time timer 13 is started by the output ON signal (ST2).
Since the start of the prohibition time timer 13 prohibits the output of the start signal from the control unit 11 during the set time, the doors 2 and 2 do not open. Since the doors 2 and 2 are not opened, if the inner opening touch switch 4 is turned on again or again (ST3), the prohibition time timer 13 is reset each time (ST4), so that it is substantially prohibited. Time is extended.
Therefore, inpatients can be made to recognize that the automatic door is locked, thereby abandoning without permission.

  When the prohibition time set by the prohibition time timer 13 elapses (ST5), the effective time timer 14 starts immediately after that (ST6). (ST7), the inner opening touch switch 4 returns to the initial state, that is, both the prohibition time timer 13 and the valid time timer 14 are turned off (ST8).

On the other hand, when it is necessary to go out, such as a staff member, or in the event of an emergency, it is necessary to open and close the automatic door A. When these are necessary, after the inner opening touch switch 4 is turned on (ST1), Wait for several seconds until the effective time timer 14 starts after the prohibition time elapses, and before the effective time elapses (ST9), the inner open touch switch 4 is turned on again (ST10), and the control is performed by the ON signal. Since the start signal is output from the unit 11, the drive engine M of the drive device 3 is started via the motor drive unit 12, and the doors 2 and 2 are opened (ST11).
Therefore, opening and closing of the automatic door A when necessary can be ensured.

In the present embodiment, since the start time of the prohibition time timer 13 is set to the time when the ON signal of the inward opening touch switch 4 is output, the following operation may be performed to start the automatic door A when necessary.
That is, after the inner open touch switch 4 is turned ON (ST1), the ON signal is maintained until the prohibition time of the prohibition time timer 13 elapses and the effective time timer 14 is started in the ON operation state. (Long press operation) When the effective time timer 14 is started (ST6), since the start signal is output from the control unit 11 by the continuous ON signal, the drive engine of the drive device 3 via the motor drive unit 12 M is activated and the doors 2 and 2 are opened (ST11).
Further, when the automatic door A is activated when necessary, the prohibition time timer 13 and the valid time timer 14 do not operate if the activation mode of the inner opening touch switch 4 is changed to the normal mode by the switching operation of the changeover switch 16. Therefore, the automatic door A can be activated when the inner opening touch switch 4 is turned on.
In order to change the start mode to the normal mode for a relatively long time rather than temporarily, it is also possible to change the set time of the prohibited time timer 13 to 0 seconds instead of the changeover operation of the changeover switch 16. .

  In the present embodiment, since the outward opening touch switch 4a is set to the normal mode, if the touch switch 4a is normally turned on from the outside, the automatic door A is activated and the doors 2, 2 are activated. Will open and you can enter. The outside open touch switch 4a can also suppress unauthorized entry from the outside by changing the activation mode to the control mode by operating the changeover switch 16a.

In the above-described embodiment, the case where the start time of the prohibition time timer 13 is set to the time when the ON signal of the inner opening touch switch 4 is output has been described. It is also possible to start the day. In that case, since it is necessary to output the ON signal by performing the ON operation again within the effective time, the opening of the doors 2 and 2 by the long press operation described above can be prohibited.
Further, in the above-described embodiment, the case where the inner opening touch switch 4 is in the control mode and the outer opening touch switch 4a is in the normal mode has been described, but the outer opening touch switch 4a is controlled in order to prohibit unauthorized entry from the outside. The mode and the inside open touch switch 4 may be set to the normal mode, and in order to prohibit unauthorized entry from both inside and outside, it is optional to set the specifications according to the application such as setting both the touch switches 4 and 4a to the control mode. It is.

Furthermore, in the above embodiment, the mode selection unit 15 is provided in the controller 7 in order to make it possible to change the activation mode of the inner opening touch switch 4 and the outer opening touch switch 4a by the changeover switches 16, 16a. Is not to be done.
It is also possible to adopt a configuration in which the changeover switches 16 and 16a are not provided. In this case, the touch switch (for example, the inwardly open touch switch 4) for setting the control mode without providing the mode selection unit 15 is prohibited. What is necessary is just to connect to the controller 7 by the system which passes the timer 13 and the effective time timer 14, and the touch switch (for example, the outward opening touch switch 4a) which makes a normal mode does not pass the prohibition time timer 13 and the effective time timer 14.
